BICYCLE SUPPORT.

SPECIFICATION forming part of Letters Patent No. 672,401, dated April16, 1901.

Application filed June 6, 1900. Serial No. 19,325. (No model.)

To ctZZ whom it may concern.-

Be it known that I, RUDOLPH AXEL, a citizen of the United States,residing at San Fraucisco, in the county of San Francisco and State ofCalifornia, have invented a certain new and useful Improvement inBicycle-Supports; and I do hereby declare the following to be a full,clear, and exact description of said invention, such as will enableothers skilled in the art to which it most nearly appertains to make,use, and practice the same.

My invention relates to improvements in bicycle-props, my object beingto provide a light, simple, and effective means of maintaining bicyclesin an uprightposition when not being ridden.

In the drawings, Figure 1 is a perspective view, in operative position,of the invention as applied to the forward portion of a bicycle. Fig. 2is a side elevation of the supporting mechanism attached to the head ofa bicycle. Fig. 3 is a plan view from above of the movable collar andsleeve by means of which the extensible leg is attached to the head ofthe bicycle.

To facilitate the description, with reference to the accompanyingdrawings, the letter A will be applied to the supporting mechanism, theletter O to the retaining-clip for holding the supporting-leg ininoperative position, and the letter D to the bicycle parts. Thecooperative minor parts of these several groups of mechanisms will bedesignated by the common letter strengthened by the addition of anumeral thereto.

In applying the supporter to a bicycle the sleeve A is attached to thehead D of the bicycle at a point near the junction of the forwardbrace-rod D by the clamping-flanges A, said flanges projecting laterallyfrom the said sleeve and extending about the same. Loosely engaging thesleeve between the flanges A is the collar A having the'lugs A thereon,between which the head A of the extensible leg is pivoted on the pin A.The slot A in the collar A acting with the pin A on the sleeve A,regulates the radial travel of the supporting-leg, and as said slotextends upon each side of the pin when the leg is in central inoperativeposition the leg can be projected upon either side of the bicycle, asdesired.

The supporting-leg consists of the tube A", into the upper end of whichthe head A is welded, the tube A telescoping into tube A and the tube Atelescoping into the tube A The collapsibility of the supporting-leg isregulated by bayonet connections between each tube-that is, the tube Ais provided with a longitudinal slot A cooperating with the pin A inhead of tube A, which arrangement is repeated in the tubes A and Arespectively.

Secured in the lower end of tube A is the foot member A, formed ofrubber or some substitute non-slipping material to rest upon the ground.The metal point A is added as a precautionary measure. On slippery wetpavements rubber will not hold; but a crack or small depression issufficient to hold the point A In operation, the supporting-leg beingdisengaged from the clip 0, it is extended, rotated on the sleeve Aagainst the stop A and braced againsttheground. It is evident thebicycle is now standing on a tripod formed bythe supporting-leg andfront and rear Wheels of the bicycle. The collarA beinglodged againstthe pin A maintainsits position radially from the head of the bicycle.The leg is maintained in its radial position with reference to its pivotA by the engagement of the head A with the collar. The radiation of thesaid leg is limited in its outward extension only, thus permitting theplacing of the foot A on the ground as near as desired to the frontwheel, an advantage where space is limited.

Preferably a wheel-lock, as 13 suitably supported upon the frame, as bythe clip B, is used in conjunction with the present prop.

I recognize the possibility of applying my device differently to theframe of the bicycle, such as looking the rear wheel and applying thesupporting-leg to upright brace between the saddle-post and crank-hangerof the bicyole-frame. Also certain mechanical changes might be made inthe construction of the posts without interfering with the spirit ofthis invention.

Having thus described this invention, what is claimed is- 1. Thecombination with a tube of a bicycle-frame, having a pin extendingtherefrom, of a collar fitting upon said tube and having a sleevebetween said flanges and provided with I a slot into which said pinprojects, said slot slot through which the said pin projects, and asupporting-leg upon said collar, the end walls of said slot formingabutments against which said pin bears to limit the movement of saidcollar to hold said leg in supporting position, substantially asdescribed.

2. The combination with the head-tube of a bicycle-frame, of a sleeveclamped about the same, laterally-extending flanges about said sleeve, apin extending from said sleeve intermediate said flanges, a collar aboutsaid extending to each side of the pin when the said collar is incentral, inoperative position, lugs upon the ends of said collar, and asupporting-leg pivoted between said lugs, the head of said leg beingadapted to engage said collar when the said leg is fully extended;substantially as described.

In testimony whereof I have hereunto set my hand this 28th day of May,1900.
